Bauder rainwater outlets.Guidance for specification option: Bauder has a range of insulated or stainless-steel rainwater outlets. The insulated outlets can be used for maintaining thermal continuity at drainage points. Suitable for warm, cold and inverted roof construction. The BRE Certified (report no. HPR357-303748) high thermal value of the rigid foam body prevents condensation from forming on the underside of the outlet body. Designed for use when connecting to conventional drainage systems and is suitable for both new build and refurbishment projects. Outlets are included in the Bauder waterproofing system guarantee as they are integrated components. Flow rate figures (where applicable) are based on BS EN 12056:3:2000, typically taken using a 35 mm header of water including leaf grille:
BauderSOLAR F XL Photovoltaic Mounting System.Guidance for specification option: Bauder flat roof PV mounting solution for framed solar modules. The mounting units are secured to the roof using a membrane-to-membrane welding technique. This installation method means that the roof is not compromised by penetrations for fixings, nor is it ballasted, which would add additional weight loading to the roof. Specifically designed to be installed on Bauder bituminous or single-ply waterproofing systems and provide a lightweight, low-risk and quick-to-install mounting solution for framed solar modules. Bauder rooflights/ glazing/ ventilation.Guidance for specification option: All these glazing products are fully compatible with the roof waterproofing systems. Consult manufacturer for details and insert requirements.
